The American Indians were led by Little Turtle of the Miamis, Blue Jacket of the Shawnees and Buckongahelas of the Delawares (Lenape). The war party numbered more than one thousand warriors, including a large number of Potawatomis from eastern Michigan and the Saint Joseph. The opposing force of about 1,000 Americans was led by General Arthur St. Clair. The forces of the American Indian confederacy attacked at dawn, taking St. Clair's men by surprise. Of the 1,000 officers and men that St. Clair led into battle, only 24 escaped unharmed. As a result, President George Washington forced St. Clair to resign his post and Congress initiated its first investigation of the executive branch.

The 1783 Treaty of Paris, which ended the American Revolutionary War (a war in which American Indian tribes were overwhelmingly allied with the British and were treated as defeated powers, following the American victory over the British), recognized United States sovereignty of all the land east of the Mississippi River and south of the Great Lakes. The Indian tribes in the Old Northwest, however, were not parties to this treaty and many of them, especially leaders such as Little Turtle and Blue Jacket, refused to recognize American claims to the area northwest of the Ohio River. The young United States government, deeply in debt following the Revolutionary War and lacking the authority to tax under the Articles of Confederation, planned to raise funds via the methodical sale of land in the Northwest Territory. This plan necessarily called for the removal of both Native American villages and squatters. During the mid and late 1780s, American settlers in Kentucky and travelers on and north of the river suffered approximately 1,500 deaths during the ongoing hostilities, in which white settlers often retaliated against Indians. The cycle of violence threatened to deter settlement of the newly acquired territory, so John Cleves Symmes and Jonathan Dayton petitioned President Washington and his Secretary of War, Henry Knox, to use military force to crush the Miami.
